Benefits of technology

This patent aims to improve existing test devices by creating a reliable, simple, and affordable design that is easy to handle and replace disposable components. The device includes a housing with a cassette compartment and an opening for sample application onto a test tape. A protective cover can be moved between a closed position and an interlocking mechanism allows the cover to securely access the opening without interfering with the device's structure. The interlocking mechanism engages with a door lock to prevent damage when the cover is in the closed position. The protective cover and its interlocking mechanism allow for easy replacement of the tape cassette without the risk of damage. The device can be easily handled and used by users or diabetics in critical physical conditions.

Problems solved by technology

Unfortunately, many such devices may not be reliable, simple or straightforward to produce via a low-cost design especially suitable for mass production.

Abstract

A test tape device is disclosed herein for use with a replaceable analytical tape cassette, where the device includes a housing having a cassette compartment covered by a cassette door and a housing opening for sample application, a protective cover that can be moved between a closed position covering the housing opening and a release position allowing access to the housing opening and a door lock for retaining the cassette door in the closed position, wherein the protective cover is coupled with the door lock via an interlocking mechanism, such that the door lock can only be unlocked in the release position of the cover.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This patent application is a continuation of Int'l Patent Application No. PCT / EP2011 / 072864; filed 15 Dec. 2011, which claims the benefit of EP Patent Application No. 10195384.2; filed 16 Dec. 2010. Each patent application is incorporated herein by reference as if set forth in its entirety.TECHNICAL FIELD[0002]The invention relates generally to engineering and electrochemistry, and more particularly to a test tape device for use of and including a replaceable analytical tape cassette such as those used in blood glucose tests.BACKGROUND[0003]Many devices are used in practice as blood glucose meters for self-monitoring by diabetics. In one example, a plurality of reactive test fields is provided on a spoolable test tape in a tape cassette. The reactive test fields are examined photometrically after an application of a small amount of a blood sample to determine the glucose content as exactly and reliably as possible. Such tape cassettes are...
